Anyone know how to work out the speed / config for a minimum radius of turn - so called corner speed I believe, more commonly used for fighting aeroplanes? I'm thinking wrt mountain flying.
I suggest you read up on your basic flying principles and specific mountain flying texts, and forget the fighter pilot stuff for a while. Minimum turn radius is had with minimum speed and maximum bank/G.
"Cornering speed" has more to do with turn RATE than radius, and also has an aspect of sustainability in it.
